No, I am using the latest version and of course I already searched this forum. So I digged and I found that when drawSeriesLineAsPath is set, the drawItem method of the renderer calls drawPrimaryLineAsPath, which only draws the path once the item index reaches state.getLastItemIndex(). The problem i...

I have an XY plot in which calling setDrawSeriesLineAsPath(true) on the
renderer causes the whole line to disappear; things work as expected
otherwise. I do not have the time to go to the bottom of this new oddity
right now but perhaps it rings a bell with someone? Thanks.

Now that's clear. Thanks a lot.

Any chance you might at some point start producing HTML release notes,
with pictures of new features (when it makes sense), rather than plain
text ones?

Thanks. How does one get there, though (assuming one was provided a direct link)?
In the Download pull-down menu, neither "Default" nor "Browse all packages" gives
the whole list.

In the NEWS file that is included in the distribution. Having to download each release to find out the history of new functionality (I haven't looked at JFreeChart since 1.0.2) is just what I want to avoid. Or in the announcement at the top of the forum [...] Or on the SourceForge downloads page, y...

Where can one find a summary of new features in each release, as opposed to the minutiae of the changelog?

Thanks.

I think I've found it: that would be the java2DToValue method of ValueAxis.

David Gilbert's answer is the one that makes sense to me. It further implies that if you extend JFreeChart classes to create new charting functionality, as I do, then you must carefully segregate them from the rest of your code (that is, in their own package and jar) lest your entire code base shoul...

I don't think there is such an automation in JFreeChart.

Every Swing widget for which it is relevant include such a method, e.g., JList.locationToIndex and JTable.rowAtPoint; it is not an unreasonable expectation.

In any case, what do you call a "data item"? How does one get its box?

Given an xy plot and a mouse click, how do I find out which point(s) are in a certain area around the click point? This is often know known as hit-testing and is related to my earlier question about which area an xy plot point occupies on the chart. More generally, the manual seems to have nothing t...

Thanks for the reference but that is still obscure. The blog entry you sent me to says: Inheritance creates derivative works in the same way as traditional linking, and the LGPL permits this type of derivative work in the same way as it permits ordinary function calls. which I take to mean that clas...

The licensing FAQ does not answer an important question, one which arises because of the antiquity of the (L)GPL, conceived in the days of C, before OO: when we extend or override a JFreeChart class, is that custom class part of our code or does it constitute an extension of JFreeChart, subject as s...

I may have missed it but I didn't find in the documentation a discussion of how to determine (or modifiy, for that matter) the area allocated to each point in xyplot. The issue arises, e.g., when writing a custom renderer. Should I assume that it is just the clipping area of the graphics object? A r...
